ANCHORING BASE FOR TRAFFIC SIGNALS. Y

Application filed October 21, 1925. Serial No. 33,995.

Our invention relates to traflic signals of the type wherein a yielding self-arighting signal post is placed in the street, and the invention is directed to an improved anchoring base adapted to be located in the pavement or roadway, and to which the base is adapted to be anchored.

The improved anchoring base is especially designed and particularly adapted for use in connection with traffic signals of the char-i acter disclosed and claimed in our prior application filed September 3, 1925, under Serial Number 54,24:O, and entitled Traflic signals. 1

' In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a view in elevation showing the anchoring base applied to support a signal post from concrete pavement, the latter being shown in section; and

Fig. 2 is an enlarged fragmentary view partly in section and partly in elevation showing the base on a larger scale than in Fig. 1.

The concrete pavement is indicated by the character 3 The base comprises an upright anchoring tube 3 preferably formed from wrought iron or steel pipe threaded at both ends. The lower end of the anchoring tube 3 is screwed onto the internally threaded hub of aflanged anchoring plate 4, and the upper end of said anchoring tube 3 is screwed into a coupling sleeve 5, the upper end of which is preferably set flush with the surface of the pavement 1 The signal post comprises a casing or rigid portion indicated as an entirety by the numeral 6, and a yielding resilient tube 7 preferably of fabric and rubber composition. This base proper may take various forms but will preferably be of the type disclosed and claimed in our prior application, above identified. 7

The numeral 8 indicates a tubular coupling or sleeve that is telescoped onto the lower end of the flexible tube 7 and is yieldingly attached thereto preferably by nut-equipped bolts 9 and an external clamping ring 10.5 This tubular coupling 8 has a downwardly projecting threaded portion that is adapted to be screwed onto the coupling sleeve '5, as

best shown in Fig. 2. The numeral 11' indithe concrete, its elements 3, 4 and 5 will be securely held together and against rotation and solidly supported against vibratory vmovements of all kinds, so that it will therefore aiford a very firm and efiicient anchor. This anchoring device is of very simple construction, may be made at small cost, its parts quickly assembled and, when applied, will not getout of adjustment nor break down. Moreover, it is vertically adjustable, so that the flanged base plate 4 may be set at different depths withln' the concrete. The con- .pling sleeve 5' should be set flush with the top of the road bed, and when the post is not applied, it should be closed with a suitable olug, so that it will not form'an obstruction 1n the road. Obviously, the post may be very quickly applied to the anchoring base or quickly removed therefrom simply by screwing the coupling tube 8 into and out of the anchored sleeve 5.

What we claim is:

A traiiic signal comprising an anchoring tube adapted to be secured in the road bed, a post-supporting coupling detachably secured to the upper end of said anchoring tube and having a rqunded and contracted upper end portion projecting above the'road bed, and a signal-post having a flexible lower end portion telescoped over the rounded portion of said coupling and rigidly secured thereto below said rounded portion.

In testimony whereof we aflix our signatures.
